It take 10 people 46 minutes to paint 3 walls. how long will it take 4 peoplr to paint 6 walls

10 people : 46 mins : 3 walls
 x2                               x2

20 people : 46 mins  : 6 walls
÷5                 x5
4 people   : 230mins : 6 walls.

So it takes 230 mins for 4 people to paint 6 walls.

230 mins = 3 hours and 50 mins


It takes 3 h 50 min for 4 people to paint 6 walls.

30

hope this helps you(:

if not plz let me know

have a good day
